Bridge Glazing Packers | Load-Spreading Support Packers

Bridge glazing packers are used in glazing rebates to create a raised support point for flat packers and sealed units. They help support the glass unit while leaving space beneath the packing point for drainage and ventilation within the frame.

Unlike a standard flat packer placed directly on the base of the rebate, a bridge packer lifts the support surface above the lower channel. This makes bridge packers useful in drained window and door systems where water escape routes and airflow paths should remain clear during installation.

Our range includes the MSBP Multi System Bridge Packer for common uPVC profile systems, along with standard bridge glazing packers in multiple widths, heights, and profiles. Popular bridge packers can be ordered online, while extended sizes and specialist bridge packers can be requested through our quote service.

Direct-order items are available for online purchase with pricing shown. Quote-only bridge packers are supplied after we confirm price, availability, and delivery time.

Choosing the Right Bridge Glazing Packer

Choose a bridge glazing packer based on the width of the glazing channel, the flat packer size being used above it, and the amount of height required inside the rebate.

Narrow bridge packers such as 12mm, 13mm, and 15mm are useful in slimmer glazing channels. Standard sizes such as 20mm, 22mm, 24mm, 26mm, and 28mm suit many common glazing applications. Wider bridge packers such as 30mm, 32mm, and 34mm are used where a broader support surface is required beneath the flat packer or sealed unit.

The packer height should be selected so the glass unit sits correctly while the lower rebate area remains clear for drainage and ventilation. Lower bridge packers are useful where only a small lift is needed, while higher bridge packers are better for deeper rebates or larger height build-up.

For general spacing and levelling, use flat glazing packers. For tightening and toe-and-heel adjustment, use wedge glazing packers. For raised support in drained glazing rebates, bridge glazing packers are the correct choice.

Trade-Grade Bridge Glazing Packers

Bridge glazing packers help installers create a stable raised packing bed inside window and door rebates. They are commonly used beneath flat glazing packers to support insulated glass units while helping maintain drainage and ventilation below the support point.

Our bridge packer range includes multiple widths, profiles, and support heights for different glazing systems. This allows installers to choose a bridge packer that suits the rebate design, glass position, and flat packer width being used.

Bridge packers can help with:

Creating a raised support point inside the glazing rebate
Supporting flat packers and sealed units correctly
Keeping lower rebate space clear for drainage and airflow
Reducing the risk of water being trapped beneath the packing point
Matching the packer width to the glazing channel or flat packer above

Direct-order bridge packers can be purchased online. Extended sizes and specialist profiles can be requested through our quote service.

Bridge Glazing Packers – FAQs

What are bridge glazing packers used for?

Bridge glazing packers are used to create a raised support platform inside the glazing rebate. They are normally used beneath flat glazing packers so the sealed unit can be supported while the lower rebate area remains clear.

What is the difference between flat and bridge glazing packers?

Flat packers provide direct spacing and support. Bridge packers lift the support point above the rebate base, which helps maintain drainage and ventilation space below the packing area.

Which bridge packer size should I choose?

Choose the bridge packer width and height based on the glazing system, rebate depth, drainage layout, and flat packer size being used above it. Wider bridge packers provide a broader support surface, while higher bridge packers provide more lift inside deeper rebates.

Are bridge packers required for all glazing installations?

No. They are mainly used where the glazing rebate is designed with drainage or ventilation paths that should not be blocked by a flat packer sitting directly on the base.

Are these compatible with modern uPVC systems?

Many bridge packers are designed for use with uPVC glazing systems, but compatibility depends on the profile and rebate design. If you are unsure, contact us with the system details and we can help you choose a suitable option.
